Probably not. Maybe they will allow for you to personally find a buyer for your shares, but the possibility that they seem to be giving us (which I wouldn't count on before we see it) is between SIAF-shareholders who have received TRW-shares;
SIAF common shareholders who have received common shares of TRW will be able to access an individualized web-page at some point prior to year-end 2018 to see their share balance displayed along with any private transactions they might initiate between themselves and buyers / sellers of TRW shares subtracted from and / or added to the balance of shares recorded under their name on November 14, 2018
You should be prepared to not really be able to sell any TRW-shares (at least not at a decent price) until 2020/2021. However, you might not want to sell your shares until then anyways; the fair valuation of TRW seems to be based on a PE of 10 or so, which is extremely low for a growth-stock
